Research for generating and detecting specially controlled light has been attracting much attention as a basic next-generation research field based on the light/light-quanta technology.

This project finally enabled the transition states of photochemical reactions as well as thermochemical reactions to be observed, which realized chemists’ long lasting dreams. In addition to the visible ultrashort pulses, the equipment for generating optimal ultrashort, high-performance pulses for spectroscopy in ultraviolet and deep ultraviolet regions were developed, and applied to the observation of elementary molecules. Also a very powerful light source for a laser microscope was developed for medical researches. This light source is necessary for researching complicated disposition and pathological processes in ecological phenomena and cells, and is one of the most suitable multicolor imaging light sources that have been desired by many researchers throughout the world. The light source developed in this project generates up to 15 colors at the same time, and is expected to measure multiple  fluorescent proteins simultaneously. Furthermore  a novel method was proposed for prepulses and postpulses to be removed in the amplification of intense pulsed lasers, by  pulse cleaning developed at the Japanese side, and it is scheduled to be implemented in the system an ultraintense amplified output from the laser systems at Max-Planck Institute.

The development of the ultrashort pulse generation and ultrasensitive, ultrawide-band detection technologies is expected to contribute to future bioscience and engineering.
